Biosensor

Abstract

There is provided a biosensor which includes: a substrate formed of an insulator; a set of electrodes provided on the substrate; a reaction part provided on the set of electrodes; a supply port for introducing blood (a specimen) to the reaction part; an attachment part for connecting the set of electrodes to a terminal of a measurement display; and a picking plate having a picking part to be picked up, the picking plate extending to a side opposite from the attachment part with respect to the reaction part and being bent in a cross-sectional direction perpendicular to the extending direction.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a biosensor that measures a specific component in a specimen.[0003]2. Description of the Related Art[0004]Conventionally, there has been proposed a biosensor that measures a blood sugar level or the like in a specimen (for example, Japanese Unexamined Patent Application Publication No. 2009-14394 A). With this biosensor, the blood sugar level or the like can be measured by measuring a current value between a working electrode and a counter electrode generated when a reaction part reacts to blood or the like introduced from a supply port. The biosensor is attached to a sensor attachment opening of a measurement display when measuring the blood sugar level or the like and detached from the measurement display for disposal after measurement.[0005]The detachment of the biosensor from the measurement display after measurement has been performed by a human hand holding the biosensor, thereby e...

AI Technical Summary

Benefits of technology

The present invention provides a biosensor with a picking plate that makes it easy to hold and measure specific components. The picking plate is designed for easy grip, reducing the distance between the reaction part and the tips of the electrodes, which can result in cost reduction. Additionally, the position regulating system can accurately position the object from which a specimen is collected, ensuring contact with the supply port of the biosensor. The technical effects of the invention are improved handling and accuracy of biosensor measurements.

Problems solved by technology

In addition, it is extremely difficult especially for the elderly and those who find it difficult to carry out detailed work with fingertips to attach a compact biosensor to the measurement display and detach the biosensor.

However, as for the biosensor described in Japanese Unexamined Patent Application Publication No. 2009-14394 A, it may be more difficult for the elderly and those who find it difficult to carry out detailed work with fingertips to, when the biosensor is taken out on a table from a storage case, hold the biosensor on the table by hand and attach it to the measurement display.

However, for the elderly and those who find it difficult to carry out detailed work with fingertips, it is difficult to precisely bring the blood on the finger into contact with the small supply port, thereby possibly making the measurement of the blood sugar level even more difficult.
